Conflict with `{shinymanager}`?

[sammerk]

{shinylogs} and {shinymanager} are awesome packages! However, I ran into an issue when combining the packages.
In the following app everything is fine, as long as line 45 is commented. But when track_usage()is active, the output freezes.

 library(shinymanager)
 library(shinylogs)
 library(shiny)
 
 credentials <- data.frame(
     user = c("fanny", "victor", "benoit"),
     password = c("azerty", "12345", "azerty"),
     comment = c("alsace", "auvergne", "bretagne"),
     stringsAsFactors = FALSE
 )
 
 # Define UI for application that draws a histogram
 ui <- fluidPage(
 
     # Application title
     titlePanel("Old Faithful Geyser Data"),
 
     # Sidebar with a slider input for number of bins 
     sidebarLayout(
         sidebarPanel(
             sliderInput("bins",
                         "Number of bins:",
                         min = 1,
                         max = 50,
                         value = 30)
         ),
 
         # Show a plot of the generated distribution
         mainPanel(
            plotOutput("distPlot")
         )
     )
 )
 
 # Wraping the UI with secure_app
 ui <- secure_app(ui)
 
 # Define server logic required to draw a histogram
 server <- function(input, output) {
 
     
     
     
     # Call of {shinylogs}
     # track_usage(storage_mode = store_json(path = "logs/"))
     
     # call the server part
     # check_credentials returns a function to authenticate users
     secure_server(check_credentials = check_credentials(credentials))
     
     
     output$distPlot <- renderPlot({
         # generate bins based on input$bins from ui.R
         x    <- faithful[, 2]
         bins <- seq(min(x), max(x), length.out = input$bins + 1)
 
         # draw the histogram with the specified number of bins
         hist(x, breaks = bins, col = 'darkgray', border = 'white')
     })
 }
 
 # Run the application 
 shinyApp(ui = ui, server = server)

Hi @sammerk ,

Thanks for reporting this issue. I've pushed a fix, if you re-install from Github, this should work.
Otherwise you have to have to exclude a special input from {shinymanager} from the logd like this :

track_usage(
  storage_mode = store_json(path = "logs/"), 
  exclude_input_id = ".shinymanager_timeout"
)
